Impact of Blanket Configuration on the Design of a Fusion-Driven Transmutation Reactor [PDF]

International Journal of Renewable Energy Development, 2018
A configuration of a fusion-driven transmutation reactor with a low aspect ratio tokamak-type neutron source was determined in a self-consistent manner by using coupled analysis of tokamak systems and neutron transport.

Structural assessment of the gripper interlock of the DEMO breeding blanket transporter. [PDF]

Heliyon, 2023
The maintenance of the DEMO Breeding Blanket (BB) remotely is a crucial aspect in development of the DEMO power plant. It is a challenge due to the huge mass of the BB segment of about 180 tons. A new concept for the BB transporter has recently been developed.
